I have setup a serverurl number on this Phone number ID 9354203d-b7e0-4bc2-bc4f-7199b9817def and not assigned a assistant to it. when a call comes in the I get a post request on my server url configured with phone number Response I am sending { "assistantId": "864e9f27-24d9-4ccf-8e25-f9289c8be403", "assistantOverrides": { "variableValues": { "key": value } }, "voice": { "provider": "11labs", "voiceId": "Fahco4VZzobUeiPqni1S", "stability": 0.75, "similarityBoost": 0.75, "style": 0.34, "useSpeakerBoost": true, "model": "eleven_multilingual_v2", "speed": 0.9 } } it says assistant id not found although is a valid ID it was working perfectly fine yesterday.

Action Step: Please verify that the assistant ID you are returning (

"864e9f27-24d9-4ccf-8e25-f9289c8be403"

) still exists and is active in your Vapi dashboard. If it was deleted or modified, you will get an "assistant ID not found" error. Example check: 1. Go to your [Vapi dashboard](https://dashboard.vapi.ai/assistants) 2. Confirm the assistant ID is present and matches your response. If the ID is missing, update your webhook response with a valid assistant ID.
